Abstract:
New classification and diagnosis criteria of age-related macular degeneration in Japan are described. The prodromal stage is classified into 1) soft drusen and 2) retinal pigment epithelial abnormalities. Age-related macular degeneration is classified into 1) exudative age-related macular degeneration and 2) atrophic macular degeneration. As specific types of exudative age-related macular degeneration, (1) polypoidal choroidal vasculopathy and (2) retinal angiomatous proliferation are also included. Diagnostic criteria include 1) prodromal stage, 2) exudative age-related macular degeneration, 3) atrophic age-related macular degeneration, and 4) exclusion criteria. The diagnosis of exudative age-related macular degeneration is certain when one of the following conditions in present: (1) choroidal neovascularization, (2) serous retinal pigment epithelial detachment, (3) hemorrhagic retinal pigment epithelial detachment, or (4) fibrotic scar in the macula.

The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...
